Several upcoming NASA missions will use lasers to increase data transmission from space. Thought your Internet speeds were slow? Try being a space scientist for a day. The vast distances involved will throttle data rates to a trickle. You're lucky if a spacecraft can send more than a few megabits per second (Mbps) - a pittance even by dial-up standards. But we might be on the cusp of a change. Just as going from dial-up to broadband revolutionized the Internet and made high-resolution photos and streaming video a given, NASA may be ready to undergo a similar "broadband" moment in coming years. The key to that data revolution will be lasers. For almost 60 years, the standard way to "talk" to spacecraft has been with radio waves, which are ideal for long distances. But optical communications, in which data is beamed over laser light, can increase that rate by as much as 10 to 100 times. High data rates will allow researchers to gather science faster, study s

Covering your download tracks isn’t the only reason to invest in a VPN service—high-profile hacks and data dumps in recent years have shone a brighter light on online security issues than ever before. It's not just public figures who are at risk, and VPNs have increased in popularity even for casual browsing due to reported extreme government surveillance. Whether it's securing your connection at the cafe down the street, or protecting your local network from prying eyes,  Private Internet Access  is one all-encompassing solution to your online safety. Like most leading VPN services, it masks your location and IP address, encrypts browsing activity, and lets you bypass regional content locks - a tool that is especially valuable while traveling. But where Private Internet Access excels is in actively blocking ads, tracking cookies, and malware—some of the primary sources for compromised privacy. Most importantly, however, Private Internet Access can’t leak any personal informa
